Four Track Cassette Tapes Out, Digital Flash Drives In

October 1, 2010 marked the end of the production of four track cassettes for the State Library's Talking Book Services (TBS) patrons. Diminishing guaranteed availability of supplies has forced this cessation of audiobook production on cassette. Now first-time produced National Library for the Blind and Physically Handicapped (NLS) audiobooks will be available only on flash memory cartridges and online.
